If you take everything personally, you'll be offended for most of your life. Remember that what most people do and say is a reflection of themselves; it has nothing to do with you.

This is the core principle of The Second Agreement from Don Miguel Ruiz’s masterpiece (The Four Agreements).
It is arguably the most liberating concept in psychology. We walk around thinking we are the protagonists of a movie called "Life," and everyone else is a supporting character reacting to us. The truth is, everyone is the protagonist of their own movie, and you are just an extra in their scene.
Here is why mastering this saves you years of suffering:
The Theory of Projection: Psychologically, people project their own reality onto others.
If someone calls you "lazy," it is often because they are obsessed with productivity and fear their own laziness.
If someone is rude to you in line, it is rarely because of you; it is because they are fighting a battle you know nothing about (a divorce, a headache, a bad childhood). Their words are a confession of their internal state, not a description of your reality.
The Trap of Agreement: You only take offense when you secretly agree with the insult. If someone walked up to you and said, "You have green skin and three eyes," you wouldn't get offended; you would think they were crazy. You would laugh. You get offended when they call you "incompetent" or "selfish" because a part of you fears it might be true. Taking it personally means you have accepted their poison as your own.
Emotional Immunity: Imagine having a superpower where insults pass right through you like a ghost. When you stop taking things personally, you become invincible. You no longer need other people’s validation to feel good, and you no longer crumble under their rejection. You realize that their opinion is just that—their opinion, filtered through their unique lens of fears and biases.
"When you are immune to the opinions and actions of others, you won't be the victim of needless suffering." — Don Miguel Ruiz
